Warning: Women Beware of Your Cycle

In a news published in Nature Magazine, it was cited that fertile women tend to be more attracted to single unattached men than married men. Whereas, women in a relationship are attracted to coupled men at nonfertile stage. This observation serves as a supporting evidence that oestrus in women which was once thought to be lost in human evolution is alive and well says Eli Finkel, a psychologist from the Northwestern University in Evanston, Illinois. Oestrus is Latin for Estrous cycle which pertains to the physiologic changes occuring in females. In mammals, it is best expressed during menstrual cycle.
